安钢150t转炉物料及热平衡计算分析与应用

Analysis and application of materials and heat balance calculation of 150t converter at Angang

以安钢150 t转炉实际生产数据为计算依据,在科学假定边界条件的基础上进行了物料平衡和热平衡计算。计算得出物料平衡钢水收得率为93.67%,误差率为0.59%,和生产实际的钢水收得率93%～95%基本一致;较为合理的热效率在80%～85%,较佳的废钢比在7%～10%。并建立了计算模型,进行了多次循环测算,得到了较科学的炉料结构配比。

Based on the actual production data of 150t converter at Angang, and on the basis of assumption that the boundary conditions in science, the material balance and heat balance were calculated. The material balance for the molten steel yield is 93.67%, the error rate is 0. 59%, and are hasicully the same with production of the actual yield of molten steel 93% ~ 95% ; The better rational heat efficiency is about 80% ~ 85% and the better scrap ratio is about 7% ~ 10%. The computing model was established for a number of cycle calculations. The more scientific structure of the charge ratio was gained.
